Zero Force Motor Replication Project

[Yaro1776]

This is 100% identical to the Monopole ZFM that I'm building except that I'm going with 4 coils.

Are you switching them all parallel with each other or putting all 6 coils in series to up the recovery voltage?

I want to see this turn a Kromrey.

Hello Aaron,

Do you have a perception as to the RPM and power requirements to run the Kromrey device? Be good to have a useful performance goal for the ZFM as the builds progress.

Hey Ron,

Very nice work in putting together the pancake ZFM design. Looking forward to the progress and performance as you go forward with the coil firing modification/position.

Love the opto couplers integrated into the firing circuit - a step up from the reed switches from a precision perspective.

Thanks for sharing your replication efforts and Happy St. Nicholas' Day,
Yaro

Ron can you post your circuit?

Six coils in series Aaron, It seems to run at 740 RPM on 5 watts. This is version one where I am switching 12 times per revolution with the H bridge.

Version two will have double the number of magnets, N S N S and switch only with the north pole over the coil... so pulsing only six times per revolution.

Here is a video of version one:

Thanks James for the interest...

What this is, is a six coil, six magnet rotor design.

The problem I felt with PL's two coil design is that it does not scale up as the gaps become too large.

So in this approach I have all one polarity magnets and fire the coils with one polarity when the magnet is over the coil and fire the coils with the opposite polarity when the magnet is in the gap.

A year ago I posted an experiment of the coil tests

https://www.youtube.com/watch?v=yC4g0XCgEqM

So as you can see there are two stages, one is the pull over the coil and the second is the repulse in and out in the gap between two coils.

Like this:

So yes bifilar (for convenience) two strands 60 feet of number 20 for each coil, in series.

Being a Turion three battery fan I was intrigued when someone suggested an updated Zero Force Motor as "the" motor.

With that in mind I have built a large two pole, a four pole and now with this model a six pole motor.
The twin rotors are just under 12 inches dia (300mm)

Hi Ron --

Nice Coil winding setup. I have a few questions for you.

What is the magnet wire gauge you are using?

What is the size of you wood coil form? (Looks a little bigger than the PVC pipe coil form but it all depends
on which side of your coil the magnet's magnetic field will cut into.)

Are you winding this coil bi-fliar?

Thanks,

-- James McDonald

Thanks James - so the input is the same.

But the output - in the diagram, the cap is connected to the ground rail just like the DC neutral output of the bridge. Was yours like that or was the DC bridge output free floating direct to a cap without any connection to the ZFM circuit?

Hi Aaron --

The output from the Full Wave Bridge is the same hooked to the capacitors but the output to the load is switched with a pair of FETs that can switch 260 amps of current. Its not a direct connection to the load like the circuit you show but its a voltage charge level that switches the voltage and current to the load.

Hello everyone
in my last post, I have committed to catch up with my results with the Zero Force Motor of Bedini
Here: https://www.youtube.com/watch?v=Ck44O9tQdLQ -- you can leave a comment; good or bad I do not care
best regard cristian alba

Can you post your circuit? It is difficult to see it in the video.

[Aaron Murakami]

Hi Aaron --

The full wave bridge circuit you show is exactly like I hooked up the Capacitor Dump Board to the Bedini-Cole type circuit. The AC input of
the full wave bridge and the output going directly to the capacitors. The spikes off the coil are not very big thus the charging was very small
although it was charging the battery. I did not take a current reading during this check and I did not see any load on the motor that you could tell by sound. All I had hooked up was voltage meters for watching the charge on the battery hooked to the back side of the capacitor dump board.

[James McDonald]

James,

Ok, so the input to the bridge was exactly like this it sounds like?



Was the output of the bridge like in the diagram or was the output isolated from the rest of the circuit going straight to an isolated cap that is not connected to the ground rail?

Also, when you were taking the recovery with the bridge, did it affect the input draw of the machine?

Hi Aaron --

I did not post a circuit but I did hook up the outside leads of the two coils to the AC input of the Full Wave Bridge on my Capacitor
Dump Board. The leads that were hooked up, if you were to measure from lead to lead you would get the full resistance of the two coils.

RS, all,

How it works:

Convention has the flux lines flowing out of the North pole into the South pole.

For the magnet (with the right polarity) at "A", it will lock into the flux lines and travel the length of the coil

For the magnet at "B", (of the same polarity) it will 'see' the out flow and will be repulsed.

For the magnet at "C", (of the same polarity) it will see the inflow and be attracted back to the coil.

For the magnet at "D", it must be of the same polarity as "A" in order to travel in the same direction.

I have re-posted the JPG as my good friend Gyula has clarified it with polarities

This was post 294

If I redraw it then it should be clear how the device works
